India: l09(Part-I): 111-112,2009 Short COlnlnunicatioll RANGE EXTENSION OF A TREE FROG POLYPEDATES TAENIATUS (BOULENGER, 1906) Polypedates taeniatus (Boulenger, 1906) was described from Purneah District of Bihar State. Subsequently, it was reported from Dudhwa National Park, Uttar Pradesh (Ray, 1991) and Orang National Park, Assam (Ahmed and Dutta 2000). Polypedates taeniatus (Boulenger, 1906) is a slender, smooth-skinned arboreal frog. The body is torpedo shaped. Snout-Vent length: 47 mm. Vomerine teeth in two oblique series between the choanae. Head a little longer than broad, snout truncate or obtusely acuminate, as long as the diameter of the orbit, concave nostril much nearer the end of the snout than the eye, inter orbital space broader than the upper eyelid, tympanum two third or three fourth the diameter of the eye. Fingers free, toes barely half webbed, disks moderately large, that of the third finger lTIeasuring about two fifth the diameter of the eye. Subarticular tubercles oloderate. Tibio-tarsal articulation reaching the eye. Skin smooth or finely areolate above, belly granular. Purplish brown above, a narrow lighter vertebral line, a broad light band frool the upper eyelid to the groin, bordered above and beneath by a dark-bown band, the lower extending over the temple and the loreal region to the end of the snout, a white streak froIn below the eye to the shoulder, no dark bars on the liITIbs, a light streak along the outer side of the tibia, lower parts white. Compared to Prnaculatus and P leuco111ystax this species differs by having narrower head with vertical lores, smaller digital disks and by absence of all traces of web between the fingers. On our survey tour in Uttar Pradesh in the month of JUly, 2008, 06 specimens of Polypedatcs taeniatus were collected. The collection data of which are given below.

  • Amphibian Community Structure Along Elevation Gradients in Eastern Nepal Himalaya Janak R
    Khatiwada et al. BMC Ecol (2019) 19:19 https://doi.org/10.1186/s12898-019-0234-z BMC Ecology RESEARCH ARTICLE Open Access Amphibian community structure along elevation gradients in eastern Nepal Himalaya Janak R. Khatiwada1,2, Tian Zhao1* , Youhua Chen1, Bin Wang1, Feng Xie1, David C. Cannatella3 and Jianping Jiang1 Abstract Background: Species richness and composition pattern of amphibians along elevation gradients in eastern Nepal Himalaya are rarely investigated. This is a frst ever study in the Himalayan elevation gradient, the world’s highest mountain range and are highly sensitive to the efects of recent global changes. The aim of the present study was to assess amphibian community structure along elevation gradients and identify the potential drivers that regulate community structures. Amphibian assemblages were sampled within 3 months in both 2014 and 2015 (from May to July) using nocturnal time constrained and acoustic aids visual encounter surveys. In total, 79 transects between 78 and 4200 m asl were sampled within 2 years feld work. A combination of polynomial regression, generalized linear models, hierarchical partitioning and canonical correspondence analysis were used to determine the efects of eleva- tion and environmental variables on species richness, abundance, and composition of amphibian communities. Results: Species richness and abundance declined linearly with increasing elevation, which did not support the Mid- Domain Model. Among all the environmental variables, elevation, surface area and humidity were the best predictors of species richness, abundance and composition of amphibians. The majority of amphibian species had narrow eleva- tion ranges. There was no signifcant correlation between species range size and elevation gradients.

The Bright frog (Humerana humeralis) and Point-nosed frog (Clinotarsus alticola) were two new records to the State of West Bengal. The detailed species accounts of these amphibian species along with their registration numbers, measurements, diagnostic features, colouration, habitat and distribution have been noted and this comprises the first comprehensive scientific document of the amphibians of the duars area of northern West Bengal.

Chetia1, D. K. Sharma1, S.

Of which 1 species belonged to family Bufonidae, 2 species to family microhylidae, 1 species to family Rhacophoradae, 6 species to family Dicroglossidaeand and 2 species to Ranidae. Morphometric study was carried out for Duttaphrynus melanostictus. Significant variation was observed in the morphometric characteristics of D. melanostictus with its Lectotype. Supratympanic fold was found to be present and parietal ridge is absent in case of specimens of Bongaigaon, while vice versa in Lectotype. Webbing formula found to be I0-1II0-1½III1-3½IV3½-1½ in case of lectotype, where as in the specimens from Bongaigaon it is I1-1½II1½-2½III1½-3½ IV3½-1½. Keywords: Amphibia, Wetland, Duttaphrynus melanostictus 1. INTRODUCTION Wetlands are one of the world's most productive and important ecosystems. The word 'wet-land' tell us that they are lands that are wet. These ecosystems fall somewhere between terrestrial and aquatic categories. They are more shallow and characterized by the presence of vegetation rather than open water.
